Amazon Web Services (AWS)

Here you will find detailed information about Amazon web services and their basic principles. It will improve your knowledge and polish your skills to appear more effectively in the real exams.

Initiate To Learn Amazon Web Services With Amazon EC2?

When you are trying to launch any application one of the major problems is to predict the computing power that is required for the proper functioning of that application. There are two options: either we will pay more for setting computing powers or we will utilize the powers more than is required and it will lead to the application crashes. To solve this problem computing clouds provide a pay-as-you-go model according to the needs of users.

Amazon elastic computing cloud is part of Amazon web services will allow users to rent virtual computers which are necessary to run any application and its processes.

Introduction of Elastic Computing Cloud EC2

Elastic computing cloud provides one of the best platforms with different choices of the latest processors. It provides elasticity to scale up and down the number of instances. You can define an instance as the smallest portion of a big computer that consists of its own operating and configuration system. There can be millions of instances in a single computer.

Reasons for Choosing Amazon EC2 for Computing Web Services

Amazon EC2 is much more convenient and easy to use. It is far better than the traditional operating systems. Start with the small instances and as the traffic increases, you can go up to the larger instances. There is no need to worry. This whole process will take a few minutes to complete.

AWS takes charge of the whole security patch procedures and updates.

Kinds of EC2 Instances

The type of any instance is decided by the nature of the application. AWS provides different kinds of instances for different workloads.

  • General-purpose instance

This type of instance is used to maintain the balance between performance and cost.

  • Compute-optimized instance

If a system requires a lot of power from the central processing unit then a compute-optimized instance is made for you.

  • Memory-optimized instance

A heavy application that does not need a lot of power from the CPU and can be processed with RAM then a Memory optimized instance is one of the best options.

  • Storage optimised instance

As the name suggests, a Storage optimised instance requires more storage for optimisation.

  • Accelerate computing

This type of instance is used for applications that require heavy graphics computing.

Pricing options for Elastic computing cloud EC2

  • On-demand instance
  • Spot instance
  • Reserved instance
  • Dedicated host
  • Dedicated instances
  • Capacity reservations

Overview of Amazon machine image

The Amazon machine image is used to create virtual machines with Amazon elastic compute clouds. It consists of ES snapshots, launch permissions and block device mapping.

Develop your own AMI

  In AMI you can design and create AMI according to your own choice by saving the configuration.

Define Elastic Block store

AWS offers an elastic block store that is attached to an instance for a network drive. EBS scales up and down without any restriction.

Persistent storage

It secures the data and prevents it from being eliminated even when the system is shut off.

There are different types of EBS volumes:

  1. Solid-state drive
  2. General-purpose SSD
  3. Provisioned SSD
  4. Hard disk drives
  5. Throughput optimized HDD
  6. Cold HDD

Procedure for Developing EC2 Instance 

  • First of all login to the AWS management platform
  • Click on the launch instance button
  • Choose the instance type
  • Enter settings according to your own choice
  • Add storage and pick the type of storage
  • Check out the settings for configuration and click on the launch button
  • After a few minutes, a new instance will be launched. So you have successfully created an EC2 instance.

Monitor Performance for EC2 Instance

It is not easy to monitor cloud infrastructure especially when you migrate servers to the cloud. Amazon has inbuilt features that help to verify monitoring in just a few minutes. Now Amazon EC2 has made it easy to create instances on the cloud. It is recommended by experts to use AWS services for monitoring.

Introduction of Cloud Watch

Cloudwatch accumulates data in the form of logs and metrics to visualize it on dashboards. You will get a complete view of operational health and complete visibility in your AWS resources. To discover insights and troubleshoot issues to run your applications smoothly.

It includes:

  • Namespace
  • Metrics
  • Dimensions
  • Statistics
  • Alarms

Compare Amazon RDS and Amazon EC2

When you migrate a database from one-premise to AWS cloud then you will come across different services. Download MySQL on any instance directly. Amazon web services also provides database services for RDS.  

  • RDS completely manages, configures and secures all the processes while EC2 controls software for managing databases and backups.
  • In comparison to EC2, RDS don’t have complete control over the systems.
  • In RDS there is an automatic system of backups. There is a need to take care of backups in EC2.
  • RDS easily works with other AWS services while EC2 can not be used to monitor performances.
  • In EC2 data is stored in EBS volume. In RDS data is saved with end-to -end encryption.

In this article we have provided all the information about Amazon web services (AWS). if you are a beginner in the field of Amazon then you will get detailed information about EC2 instances and its attachments to proceed successfully in the professional career.
